For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using
the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer"
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies"
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects
and people.
CAUTION: Medical electrical equipment requires special precautions regarding EMC and
must be installed and operated according to these instructions. It is possible that high
levels of radiated or conducted radio-frequency electromagnetic interference (EMI)
from portable and mobile RF communications equipment or other strong or nearby
radio-frequency sources, could result in performance disruption of the system. Evidence
of disruption may include image degradation or distortion, erratic readings, equipment
ceasing to operate, or other incorrect functioning. If this occurs, survey the site of
disruption, and take the following actions to eliminate the source(s).
• Turn equipment in the vicinity off and on to isolate disruptive equipment.
• Relocate or reorient interfering equipment.
• Increase distance between interfering equipment and your system.
• Manage use of frequencies close to the system frequencies.
• Remove devices that are highly susceptible to EMI.
• Lower power from internal sources within the facility control (such as paging
systems).
• Label devices susceptible to EMI.
• Educate clinical staff to recognize potential EMI-related problems.
• Eliminate or reduce EMI with technical solutions (such as shielding).
• Restrict use of personal communicators (cell phones, computers) in areas
with devices susceptible to EMI.
• Share relevant EMI information with others, particularly when evaluating
new equipment purchases which may generate EMI.
• Purchase medical devices that comply with IEC 60601-1-2 EMC Standards
(3V/meter EMI immunity, limit interference level to 0.0014 V/meter)
